Self-harming and self-sabotaging behaviors, from skin picking to ghosting people, all stem from evolutionary survival mechanisms, according to a compelling new psychological analysis.

For the first time, scientists have reconstructed ancient genomes of Human betaherpesvirus 6A and 6B (HHV-6A/B) from archaeological human remains more than two millennia old.

Circadian rhythms that are weaker and more fragmented are linked to an increased risk of dementia, according to a new study published on December 29, 2025, in Neurology®, the medical journal of the American Academy of Neurology.

Placenta accreta spectrum (PAS) used to be a rare pregnancy condition, but it now affects roughly 14,000 pregnancies annually, posing a major cause of maternal death.

A new University of Toronto-led study has discovered a possible biomarker linked to multiple sclerosis (MS) disease progression that could help identify patients most likely to benefit from new drugs.

As cesarean delivery (C-section) rates continue to rise worldwide, experts at NYU Langone Health are highlighting a surgical technique that may help lower the risk of long-term complications.

In a new study, Christine Agdestein has surveyed several aspects of the postnatal check-up. Agdestein is a specialist in general practice and a general practitioner, and is currently a PhD candidate at the Norwegian University of Science and Technology (NTNU).

When food prices skyrocket during an economic crisis, it is primarily urban populations and people with low levels of education who are affected.

Cleveland Clinic researchers have discovered that bacteria inside cancerous tumors may be key to understanding why immunotherapy works for some patients but not others.

Within tumors in the human body, there are immune cells (macrophages) capable of fighting cancer, but they have been unable to perform their roles properly due to suppression by the tumor.

A newly identified and rare genetic variant slows the growth of mutated blood stem cells, researchers report, and it reduces the risk of leukemia.

A novel iLDS statistic uncovers adaptive gene sweeps in gut bacteria, highlighting evolutionary responses to modern diets and enhancing microbiome studies.

Depression was associated with a higher likelihood of chronic headaches in Iranian adults, with statistical models identifying body mass index and dietary iron intake as partial mediators. Physical activity was linked to depression but did not independently mediate headache outcomes, highlighting interconnected, non-causal pathways.

With a new study in the journal Science Bulletin, researchers at Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University have discovered a new way that aggressive breast cancer cells escape the immune defenses.

This exploratory study in healthy young adults found that plasma sodium levels within the normal clinical range are significantly associated with resting motor threshold, an indirect measure of corticospinal excitability. Lower sodium concentrations were linked to lower thresholds, suggesting subtle physiological variation in electrolytes may relate to interindividual differences in brain excitability.

In the realm of modern medicine, RNA-based therapies have emerged as a promising avenue, with significant advancements in metabolic diseases, oncology, and preventive vaccines. A recent article published in Engineering titled "The Future of AI-Driven RNA Drug Development" by Yilin Yan, Tianyu Wu, Honglin Li, Yang Tang, and Feng Qian, explores how artificial intelligence (AI) can revolutionize RNA drug development, addressing current limitations and offering new opportunities for innovation.

Plastic pollution does more than litter landscapes and oceans. According to a new perspective article published in Biocontaminant, viruses living on plastic surfaces may play an underrecognized role in spreading antibiotic resistance, raising concerns for environmental and public health worldwide.

A recent study published in Engineering has unveiled a novel approach to generating functional organoids from human adult adipose tissue.

A recent study published in Engineering has shed new light on the role of the protein NSUN2 in the development of cardiac hypertrophy and heart failure.

The rise of private equity firms investing in health care facilities across the United States has been exploding in the last decade.
